SX4 MOTORIZED TREADMILL  
POWER REQUIREMENTS  
Power Requirements:  
IMPROPER CONNECTION OF THE EQUIPMENT GROUNDING CONNECTOR CAN RESULT IN A RISK OF AN  
ELECTRIC SHOCK. CHECK WITH A QUALIFIED ELECTRICIAN OR SERVICE MAN IF YOU ARE IN DOUBT AS  
TO WHETHER THE PRODUCT IS PROPERLY GROUNDED. DO NOT MODIFY THE PLUG PROVIDED WITH  
THE PRODUCT, IF IT WILL NOT FIT THE OUTLET; HAVE A PROPER OUTLET INSTALLED BY A QUALIFIED  
ELECTRICIAN.  
This treadmill can be seriously damaged by sudden voltage changes in your home’s electrical power. Voltage  
spikes, surges and noise interference can result from weather conditions or from other appliances being turned on  
or off. To reduce the possibility of treadmill damage, always use a surge protector (not included) with your  
treadmill.  
Surge protectors can be purchased at most hardware stores. The manufacturer recommends a single outlet  
surge protector with a UL 1449 rating as a Transient Voltage Surge Suppressor (TVSS) with a UL suppressed  
voltage rating of 400V or less and an electrical rating 110VAC, 15 amps.  
This treadmill must be grounded to reduce the risk of electrical shock. Grounding provides a path of least  
resistance for electric current, should the treadmill malfunction. This treadmill comes with an electrical cord having  
an equipment-grounding conductor and a grounding plug. Always plug the power cord into a surge protector, and  
plug the surge protector into an appropriate outlet that is properly installed and grounded in accordance with all  
local codes and ordinances.  
This product is for use on a nominal 110-volt circuit, and has a grounding plug that looks like the plug illustrated in  
the drawing below. GFCI outlets and GFCI Circuit Breakers are NOT recommended for use on this product. GFCI  
outlets and GFCI Circuit Breakers may cause this equipment to function improperly.

MAINTAINENCE  
CLEANING:  
Routine cleaning of your treadmill will extend the product's life.  
Warning: To prevent electrical shock, be sure the power to the treadmill is OFF and the power cord  
is unplugged from the wall electrical outlet before attempting any cleaning or maintenance.  
Important: Do not use abrasives or solvents to clean the treadmill. To prevent damage to the  
computer, keep liquids away and keep it out of direct sunlight.  
After each workout: Wipe off the console and other treadmill surfaces with a clean, water  
dampened soft cloth to remove excess perspiration.  
Weekly: Use of a treadmill mat is recommended for ease of cleaning. Dirt from your shoes contacts  
the belt and eventually makes it to underneath the treadmill. Vacuum underneath treadmill once a  
week.  
DECK LUBRICATION:  
The walking belt has been pre-lubricated at the factory. However, it is recommended that the walking board be  
checked periodically for lubrication to ensure optimal treadmill performance. Your treadmill should not have to be  
lubricated usually within the first 400 hours of use.  
Every 2 months of operation lift the sides of the walking belt and feel the top surface of the walking board as far  
as you can reach. If you feel signs of silicone, no further lubrication is required. If it feels dry to the touch, follow  
the instructions below.  
To purchase lubricant kit please contact Smooth Fitness 1-888-800-1167  
To apply lubricant to the walking belt:  
1. Position the walking belt so that the seam is located on top and in center of the walking board.  
2. Insert the spray nozzle into the spray head of the lubricant can.  
3. While lifting the side of the walking belt, position the spray nozzle between the walking belt and the board  
approximately 6" from the front of the treadmill. Apply the silicone spray to the walking board, moving  
from the front of the treadmill to the rear. Repeat this on the other side of the belt. Spray approximately  
1/4 bottle (supplied with treadmill ) each side..  
4. Allow the silicone to "set" for 1 minute before using the treadmill.  
Apply from front to back.

IMPORTANT STEPS  
Warning:  
Before using this product, please consult your personal physician for a complete physical examination. Frequent and  
strenuous exercise should be approved by your doctor first. If any discomfort should result from your use of this product, stop  
exercising and consult your doctor. Proper usage of this product is essential. Please read your manual carefully before  
exercising.  
Please keep all children away from the equipment during use and when equipment is unattended.  
Always wear appropriate clothing, including athletic shoes, when exercising. Do not wear loose clothing that  
could become caught during exercising.  
Make sure that all bolts and nuts are tightened when equipment is in use. Periodic maintenance is required on all exercise  
equipment to keep it in good condition.  
Before beginning:  
How you begin your exercise program depends on your physical condition. If you have been inactive for  
several years, or are severely overweight, you must start slowly and increase your time gradually, a few  
minutes per week.  
Initially you may be able to exercise only for a few minutes in your target zone. However, your aerobic  
fitness will improve over the next six to eight weeks. Don’t be discouraged if it takes longer. It’s important to  
work at your own pace. Ultimately, you’ll be able to exercise continuously for 30 minutes. And the better  
your aerobic fitness, the harder you will have to work to stay in your target zone. But remember these  
essentials:  
Contact your physician before starting a workout or training program. Have your doctor review your  
training and diet programs to advise you of a workout routine you should adopt.  
Begin your training program slowly with realistic goals that have been set by you and your doctor.  
Supplement your program with some type of aerobic exercise such as walking, jogging, swimming,  
dancing and/or bicycling. Monitor your pulse frequently. If you do not have an electronic heart rate  
monitor, have your physician show you the proper way to manually check your pulse by using your  
wrist or neck. Establish your target heart rate based on your age and condition.  
Drink plenty of fluids during the course of your routine. You must replace the water content lost from  
excessive exercising to avoid dehydration. Avoid drinking large amounts of cold liquids. Fluids  
should be at room temperature when consumed.

IMPORTANT STEPS  
Warning:  
Before using this product, please consult your personal physician for a complete physical examination. Frequent and  
strenuous exercise should be approved by your doctor first. If any discomfort should result from your use of this product, stop  
exercising and consult your doctor. Proper usage of this product is essential. Please read your manual carefully before  
exercising.  
Please keep all children away from the equipment during use and when equipment is unattended.  
Always wear appropriate clothing, including athletic shoes, when exercising. Do not wear loose clothing that could become  
caught during exercising.  
Make sure that all bolts and nuts are tightened when equipment is in use. Periodic maintenance is required on all exercise  
equipment to keep it in good condition.  
Before beginning:  
How you begin your exercise program depends on your physical condition. If you have been inactive for several years, or  
are severely overweight, you must start slowly and increase your time gradually, a few minutes per week.  
Initially you may be able to exercise only for a few minutes in your target zone. However, your aerobic fitness will improve  
over the next six to eight weeks. Don’t be discouraged if it takes longer. It’s important to work at your own pace. Ultimately,  
you’ll be able to exercise continuously for 30 minutes. And the better your aerobic fitness, the harder you will have to work to  
stay in your target zone. But remember these essentials:  
Contact your physician before starting a workout or training program. Have your doctor review your training and diet  
programs to advise you of a workout routine you should adopt.  
Begin your training program slowly with realistic goals that have been set by you and your doctor.  
Supplement your program with some type of aerobic exercise such as walking, jogging, swimming, dancing and/or  
bicycling. Monitor your pulse frequently. If you do not have an electronic heart rate monitor, have your physician  
show you the proper way to manually check your pulse by using your wrist or neck. Establish your target heart rate  
based on your age and condition.  
Drink plenty of fluids during the course of your routine. You must replace the water content lost from excessive  
exercising to avoid dehydration. Avoid drinking large amounts of cold liquids. Fluids should be at room temperature  
when consumed.

TARGET HEART RATE  
Finding your pulse:  
To make sure your heart is beating in its target zone, you’ll need to know how to monitor your heart rate. The easiest way is  
to feel the pulse in the carotid artery on either side of your neck, between the windpipe and the large neck muscles. Count  
the number of beats in ten seconds, and then multiply that number by six. This gives you the number of beats per minute.  
How fast should your heart beat during aerobic exercise? Fast enough to reach and stay in its “target zone,” a range of beats  
per minute that is largely determined by your age and physical condition. To determine your target zone, consult the chart  
we have provided.

AGE IN YEARS  
ADVANCED: Sports, athletic conditioning or interval training  
FITNESS: Optimal training, aerobic or cardiovascular  
HEALTH: Beginner, low intensity with long duration produces fat burning  
You can calculate the target-heartrate for your training as follows:  
Maximum heartrate = 220 minus age  
For the different trainingtargets you should train with the following percentage of your maximum heartrate:  
HEALTH:  
50 – 70% of your max. heartrate  
70 – 80% of your max. heartrate  
80 – 90% of your max. heartrate  
FITNESS:  
ADVANCED:  
Example:  
You are 25 years old and want to train for the target Fitness:  
220 – 25 = 195  
70% of 195 = 136.5  
80% of 195 = 156  
Your target-heartrate should be between 136.5 and 156 beats per minute.  
Aerobic exercise:  
Is any sustained activity that sends oxygen to your muscles via your heart and lungs. It will improve the fitness of your lungs  
and heart: your body’s most important muscle. Aerobic fitness is promoted by any activity that uses your large muscle  
groups - arms, legs or buttocks, for example. Your heart beats quickly and you breathe deeply. An aerobic exercise should  
be part of your entire exercise routine.

STRETCHING ROUTINE  
Warm up and cool down:  
A successful exercise program consists of a warm-up, aerobic exercise, and a cool-down. Do the entire program at least two  
and preferably three times a week, resting for a day between workouts. After several months, you can increase your  
workouts to four or five times per week.  
Warming up is an important part of your workout, and should begin every session. It prepares your body for more strenuous  
exercise by heating up and stretching out your muscles, increasing your circulation and pulse rate, and delivering more  
oxygen to your muscles. At the end of your workout, repeat these exercises to reduce sore muscle problems. We suggest  
the warm-up and cool-down exercises on the following pages:  
Toe Touch:  
Slowly bend forward from your waist, letting your back and shoulders relax as you  
stretch toward your toes. Reach down as far as you can and hold for 15 counts.  
Shoulder Lift:  
Lift your right shoulder up toward your ear for one count. Then lift your left  
shoulder up for one count as you lower your right shoulder.  
Head Roll:  
Rotate your head to the right for one count, feeling the stretch up the left side of  
your neck. Next, rotate your head back for one count, stretching your chin to the  
ceiling and letting your mouth open. Rotate your head to the left for one count,  
and finally, drop your head to your chest for one count.

Sit with the soles of your feet together with your knees pointing outward. Pull your  
feet as close into your groin as possible. Gently push your knees towards the  
floor. Hold for 15 counts.  
Side Stretch:  
Open your arms to the side and continue lifting them until they are over your head.  
Reach your right arm as far upward toward the ceiling as you can for one count.  
Feel the stretch up your right side. Repeat this action with your left arm.  
Calf-Achilles Stretch:  
Lean against a wall with your left leg in front of the right and your arms forward.  
Keep your right leg straight and the left foot on the floor; then bend the left leg and  
lean forward by moving your hips toward the wall. Hold, and then repeat on the  
other side for 15 counts.
